CAR-HEATER.

SPECIFICATION forming part of Letters Patent N0. 374,020, dated November29, 1887. Application filed May a, 188%. Serial No. 237,330. (No model.)i

To all whom, it may concern;

Be it known thatl, JEROD TYLER, of St. Marys, inthe county ofElk andState of Pennsylvania, have invented a new and Improved Oar-Heater, ofwhich the following is a full, clear, and exact description. The objectof my invention is to provide a new and improved car-heater which is'fireproof and is thus prevented from setting the car on fire in case ofa collision or other accident.

The invention consists in the construction and arrangement of variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed oritin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a central sectional elevation of my improvement. Fig. 2 is aperspective view, with parts broken out, of part of my improvement. Fig.3 is a similar view oft-he lower part of the same. Fig. 4 is a sectionalside elevation of the upper part of my improvement, showing severalparts in an open position; and Fig. 5 is a cross-section of the same onthe line x :r of Fig. 4, showing the valve of the fire-extinguishingdevice closed. a

The heater A of my improvement is of suitable size and material, andprovided with the usual interior arrangement of grate-bars B, having arack, B, on their under sides, and with said rack B meshes a pinion, Bsecured to a rod, B extending outward and provided on its outer end witha handle, B for shaking said grate-bars B. The heater A is also providedwith the main door 0, adapted to slide in the guides O, and secured in aclosed position by a suitable lock, 0 The rearward motion of said door 0is limited by a stop, G thus preventing the door from falling out of theguides 0 when the door is opened. Below the main door 0 is placed thedamperdoor D, sliding in suitable guides, D, secured to the outside ofthe heater A, and in the damper-door is formed an aperture, Dregistering with an aperture, D formed in the shell of the heater A, andopening directly In .the bottom of the heater is formed the ashpit E,provided-in front with the usual ash-pit door, E, located below thedamperdoor D.

The heater A is placed in a cylindlical casing, F, made preferably ofstrong boiler-iron, and is provided with'the heavy base F, on which issecured, in any suitable manner, the base of the heater A. The casing Fis provided with three horizontal partitions, F F

and F,- and also with a top plate or cover, F which cover and partitionsare firmly secured by bolts or other suitable means to the shell of thecasing F. In the middle of the top plate, F is hinged a door, F, openingoutward, and on the side of the'casing F is hinged the main door F whichopens directly upon the front of the heater'A, so as to give access tothe doors 0. D, and E of the heater A. The partition F rests on the topplate of the heater A, and said partition supports the fuelextinguishingdevice G, provided with the vessel G, having in its bottom a threadedapertured'outlet, G passing through said partition F and. screwing on athreaded projection, A", formed on the top plate of the heater A. Saidprojectionis provided with an aperture, A leading to theinterioroftheheater A.

On the inner end of the outlet G is formed a seat for the valveGflprovided with the upwardly-extending short stem G, having a slot Gthrough which passes the pin H,secured to the lower hollow part of thevertical rod H,

in which said stem G is held and adapted to slide vertically. On theupper end of thestem G presses a spring, H", held in the hollow part'G", which extends to the outside of the casing F and carries at itsouter end an upwardly-extending cup, G, which serves for filling thevessel G with a fire-extinguishing fluid of suitable ingredients.

An outlet-pipe, G is secured to the vessel G,near its bottom,and extendsto the outside of the casing F. The pipe G is provided be tween thevessel G and the casing F with a valve, G, connected withand operated bythe rod G extending to the outside of the casing F. This pipe G servesto withdraw from the vessel G part of the extinguishingfluid wheneverdesired. The rod H passes'through the top of the vessel G and throughthe partition F, extending a suitable distance above the latter. On thisupper part of the rod H is coiled a spring, H resting with one end onthe partition I and with its other end presses against the arm I,secured by one end to the upper end of the rod II and being bentdownward to within a short distance of the upper face of the partitionF. The arm Iextends to one side of the casing F and is guided at itsouter end in guides I, secured to the inside of the shell of the casingF. The arm I is held in its lowermost position by the bolt J, mounted toslide in the keeper J, fastened to the partition F". One end of the boltJ engages the top ofsaid arm I, and theotherend of the bolt J isconnected by the link J with the short end of the bellcrank lever J,pivotally mounted in the bearing J, secured to the up per face of thepartition F. The outer end of the long arm of the bell-crank lever J isconnected with an arm, K, extending from the lever K, fulcrumed on thebearing K secured to the top of the partition I On the long end of thelever K is secured a rod, K, which extends upward and carries at itsupper end a cup, K, passing through an opening formed in the partitionF. \Vhen the long end of the lever K is inits lowermost position, thenthe cup K* is guided in said opening in the partition F, and the cupsupports at its upper end a heavy ball, L, placed so that when the shellF receives ashock from a collision or other accident then the ball L isthrown off of the cup K and rolls upon the partition F. To the other endof the lever K, next to the arm K, is secured an upwardlyexteuding pinor rod, K on which is coiled a spring, K, resting with one end on theouter end of the lever K, and with its other end against the under sideof, a'brackct, K secured to the inside of the shell F. The bracket K isprovided with a slot, K, into which projects the upper end ofthe rod Kso that when the lever K oscillates onits fulcrum the rod K moves insaid slot IQ.

To the arm I is secured a downwardly-extending rod, N, which passesthrough suitable slots in the partitions F and F, and is pivotallyconnected at its lower end with the crank-arm N, secured to the shaft 0,mounted in the standards 0, secured to the base F of the shell F. Therod N is guided in and passes through a plate, N", adapted to slidesidewise in guides N, secured to the top of the partition F.

On the shaft 0 is secured the upwardly-ea tending crank'arm P, pivotallyconnected at its upper end with the bar 1?, passing into the heater Anear its top,and carrying at its inner end a plate, I having anaperture, Pfladapted to register with the opening A of the projection AThe plate I? is supported and held in close contact with the projectionA by the guides P, secured to the under side of the top plate of theheater A.

On the shaft 0 is also secured the upwardlyextending arm Q, connected atits upper end by the link Q with the plate Q, adapted to slide acrossthe inner opening of the smokeoutlet flue A,leading from the upper endof the heater A to the outside after passing through the shell F.

On the shaft 0 is secured the downwardlyextending crank-arm R, connectedby the link It with the damper-door D, and on the shaft 0 is alsofastened the downwardly-extending crank-arm S, connected by the link Swith the lever S mounted to swing horizontally on the bearing S, securedto the base F of the casing F. The outer end of the lever S is pivotallyconnected with the circular band T, provided with a suitable number ofplates,T, adapted to slide on the upper edge of the ring F secured tothe top of the base F. One of the plates T is provided with an aperture,T, adapted to register with the hotair fiue U,opening into the casing Fand leading to the sides of the car, extending under the seats of thesame, and the other plate, T, registers with the cold-airinlet flue U,extending to the top of the car.

To the end of the arm I next to the guides I is secured the rod V, whichextends upward and passes through the partition F and the top plate, FThe part of the rod V extending above the top part, 1 is provided withracktceth V, meshing into the pinion V, secured to the wick-rod \Vof thelamp XV, preferably held on the outside of the top plate, F". Lamps mayalso be placed on the roof of the car in the usual manner, and then therod V is extended to or connected in some suitable manner with thewick-rod W, so that when the rod V is moved the wick-rod IV is turned insuch a direction that the wick moves inward, thus extinguishing thelight of the lamp.

The operation is as follows: When the carheater is in the position shownin Figs. 2, 3, and 5, then the valve G closes the outlet G of the vesselG, the latter being filled with a fireextinguishing fluid introducedinto the vessel through the cup G and the pipe G. The Valve GI remainsclosed. The valve G is in a closed position, being held therein by therod H, locked in its lowermost position by the bolt J engaging the topedge of the arm I, thus holding the spring H in a compressed condition.The bolt J locks the arm I on account of its connection with the leverK, which is weighted down at its long end by the ball L resting on thecup K", the ball L being of such a weight as to over-balance the springK", which is consequently compressed. The shaft 0 is held by the rod Nin sucha position that the apertures T in the plates T register with thepipes U, whereby the heat radiating from the heater A passes into thecar and along the same under the seats through said pipes U. Thedamper-door D is in such a position that its aperture D registers withthe aperture D in the shell of the heater A, thereby admitting the airnecessary for the combustion of the fuel on the grate-bars. The positionof the shaft 0 and its crank-arms P and Q is such that the plate Pcloses the aperture A of the projection A while the plate Q is removedfrom the opening of the smoke-flue A, and thus permits a free escape ofthe smoke arising from the burning fuel in the heater A. The latter ischarged from the outside by the operator first opening the door F of thecasing F and then unlocking the main door 0, so that the latter can beopened and fuel thrown into the fire-box of the heater, after which thedoor is again closed andlocked by the lock 0'. The door F of the casingF is then closed again and locked by any suitable means. The grate-barsB can be shaken from the outside, whenever it is necessary, by movingthe arm B forward and backward, so as to impart an oscillating motion tothe shaft- B which, by its pinion B engaging the rack B, imparts aswinging motion to the grate-bars B. If the heater now receives a shockby a collision of the car in which it is located, or by any otheraccident, then the ball L is thrown from the cup K and rolls upon thepartition Ft The lever K is thus relieved from the weight on its longend, so that the spring K forces the short end of the lever K downwardand the long end upward. This motion imparts a swinging motion by meansof the arm K to the bell-crank lever J whereby the bolt J is withdrawnfrom the arm I, and the latter and the rod H are forced upward by theaction of the compressed spring II. This upward motion of the rod Hunseats the valve G and the upward motion of the arm I imparts aswinging motion to the shaft 0 by means of the rod N and the crank-armN. The motion of the shaft 0 causes the crank-arm P to move the rod Pand its plate inward until the aperture P in the plate P registers withthe aperture A in the projection A and as the valve G3 is unseated atabout the same time, the fire extinguishing fluid in the vessel G nowfalls through the apertures A and 1 into the heater and upon the burningfuel, thus extinguishing the fire in the heater. At the same time thecrankarm Q moves the rod Q inward, so that the plate Q closes thesmoke'flue A, and the motion of the shaft 0 causes the crank-arm R tomove the damper-door D sidewise sufficiently so that the aperture D willnot register with aperture D thereby shutting off the draft. Thecrank-arm S, by its connection'with the shaft 0, imparts a swingingmotion to the lever S, so that the circular band T causes the plates Tto slide until the apertures T in said plates are moved entirely fromthe openings of the fines U and U, whereby the latter are closed 'by theplates T, and the heated air is prevented from passing into the carthrough the fiues U, and the cold airis prevented from entering thecasing F. The upward motion of the arm I causes the rod V to turn thewickrod W, so that the light of the lamps is extinguished. It will beseen that as soon as the ball L is thrown, from whatever cause, from thecup Kfithen the burning fuel in the heater and the lights in the car areextinguished, the

escape of smoke from the heater is prevented,

the hot air generated in the heater is prevented from passing into thecar through the fines U, and the draft necessary for combustion is shutoff,.thus making the device entirely fire-proof, as nothing can escapefrom the heater which might set fire to the car.
